GRAMM . . . COURTING THE ROLLERBLADE VOTE

IfPhil Grammis built for comfort, Wendy Gramm is built for speed. Inspired by GOP presidential candidate Lamar Alexander's walk across New Hampshire, the Texas senator's wife plans, beginning Monday, to rollerblade across Maryland for four days to call attention to her husband's run for the White House. (She'll make nightly pitstops for political rallies.) A Gramm spokesman said the candidate applauds his wife's enthusiasm but has no plans to take up the sport.
